Anemia is one type of red blood cell disorder. A lack of the mineral iron in your blood usually causes this disorder. Your body needs iron to produce the protein hemoglobin, which helps your red blood cells carry oxygen from your lungs to the rest of your body.
Heat transfer refers to the physical process by which heat energy moves from one area to another. The Heat Transfer Methods figure above illustrates various heat transfer methods. Branches above the fire are receiving heat by convection and radiation.
A transfer of thermal energy occurs only through 3 modes: conduction, convection, and radiation. Each mode has a different mechanism and rate of heat transfer, and thus, in any particular situation, the rate of heat transfer depends on how much a certain mode is prevalent.onvection involves the transfer of thermal energy in a moving medium â the hot gas/liquid moves through the cooler medium(normally due to density differences). Radiation involves the transfer of thermal energy by electromagnetic radiation. The sun is a good example of energy transfer through a (near) vacuum.
